Sons new room

We are expecting our daughter July 13th so my two sons had to move down stairs I built each of them a new bedroom and one is western theme so unrelated (we are dairy farmers) and the other one wanted hot rods thought id share his bedroom wall think it turned out pretty cool he took a bunch of decore from my shop but when he outgrows the bedroom theme if he ever does I'll get it all back right? Lol he loves it at 6yo
